Definitions

  • the present invention relates to a device for removing gas, vapor, particulate, or mixed type pollutants, and more particularly, to a range hood generates two air curtains above the counter top so as to remove pollutants between the two air curtains.
  • kitchens, laboratories or dust factories generate gas with grease particles or toxic gases which are harmful to the people in the sites and pollutes the surroundings.
  • the hood 10 is fixed to an underside of the cabinet 15 in which a pipe 12 is received.
  • the pipe 12 guides the gas sucked by the hood from the cook ware and expel the gas out of the kitchen.
  • the cabinet 15 is connected with other cabinet 16 on the wall 14 to which the hood 10 is connected and the other wall 13 that is perpendicular to the wall 14 is in contact with a side of the hood 10.
  • the oven 18 is installed in the counter top 17 and includes two burners 19.
  • the counter top 17 is connected on the top of yet another cabinet 20.
  • the hood 10 includes two suction fans 11 which are located above the burners 19 so as to suck the gas from the cook ware into the hood 10 and the gas can be expelled out side of the kitchen via the pipe 12.
  • the conventional range hoods 10 used in kitchens are similar to a canopy hood which is used in working sites.
  • the upward speed of the gas flow decreases quickly with the increase of the downward distance beneath the suction face.
  • the upward velocity becomes negligibly small and the suction force would not be large enough to draw effectively the gas. Therefore, the effective suction distance beneath the canopy hood is generally within about 1.5 times of the diameter of the suction opening.
  • the gas flow can easily be affected by drafts such as the air flows generated from fans, air conditioning device, people walking by, opening or closing doors or windows, etc.
  • the hood cannot be installed too low because movements and operations of cook wares or apparatus by hands or tools in the room between the table top and the canopy hood are commonly required. Because that the draft currents generated by fans, air conditioning device, people walking by, opening or closing doors or windows almost exist around the hood all the time, the conventional hood therefore can hardly have satisfied performance.
  • Fig. 15 shows an improved rang hood wherein three cross-flow fans 21 are installed on the front side, left side, and right side of the oven to provide three upward-issuing slot jets.
  • This design is aimed to use the three cross-flow fans 21 cooperated with the back wall to reduce the negative effects of the draft currents generated in the environment.
  • the pollutants around the lower portion of the enclosed area would present unsteady, chaotic flow motions with violent three-dimensional tumbling and swirling vortices. The reason why this arrangement would inevitably induce instability of flow is because of the unbalanced mass and momentum conservation laws.
  • the induced turbulent dispersion would therefore reduce the efficiency of pollutant removal through the canopy hood installed at a distance above the oven. Because the residence time of the grease particles and pollutants staying around the area above the oven becomes much longer due to the vortical motion of the flow, it becomes very dangerous when the draft currents pass over - the high-concentration grease particles and pollutants accumulated in that area may be dispersed by the cross flow. Besides, the chaotic motions of the vortical flow structures induced by the three cross-flow fans may affect the flames of the burners, e.g., drift or extinguishment of flames, and reduce the burning efficiency.
  • the conventional kitchen hoods cannot effectively remove the pollutants and this is because of the poor fluid dynamics of the air flow that the conventional kitchen hoods generate.
  • the primary object of the present invention is to provide a gaseous, vapor, particulate, or mixed type pollutant removing device which includes two elongate air blow devices installed on the front and rear ends of the counter top and an elongate suction device located at a distance above the counter top and between the two air blow devices so as to form two air curtains such that the gaseous, vapor, or particulate type pollutants generated between the two air curtains can be effectively sucked by the elongate suction hood installed above the counter top.
  • the compensation air is naturally provided into the capture zone from two "open sides" of the dual-air curtain so that the flow field would behave more like "two-dimensional" although in strict sense it is not.
  • the three-dimensional, unsteady tumble and swirl vortical flows would not appear so that the pollutants generated between the two air curtains can be effectively sucked by the elongate suction device located at a distance above the counter top and the influences on the flames can be reduced.
  • the present invention relates to a pollutant removing device which comprises first and second air blow devices which are respectively located at a front end and a rear end of a pollution source on a counter top as well as a suction device is located above the counter top and includes at least one elongate suction opening which is connected with a suction machine.
  • the first and second air blow devices respectively may also be elongate air blow slots so as to blow air upward.
  • the elongate suction opening(s) of the suction device located above the counter top is parallel to the first and second elongate air blow slots.
  • the first and second elongate air blow slots issue upward two planar jets and drawn by the at least one elongate suction opening of the suction device to form two air curtains so that the pollutants between the air curtains would be less affected by the draft currents existing in the environment.
  • the at least one elongate suction device draws the pollutants encapsulated between the two air curtains out to the outdoors through the suction opening(s).
  • Figs. 1A-1C show the hand sketches of the simplified flow fields associated to a planar jet, a suction slot, and a combination of the jet and the suction slot, respectively.
  • a jet 50 is ejected from a nozzle 51 from the left to the right.
  • the jet 50 therefore will expand outward in the downstream area.
  • the fashion of expansion will depend on the characteristic regimes of Reynolds number. Downstream the nozzle 51 within a distance about 80 nozzle diameters, the momentum conservation usually is observed.
  • the jet may expand, break up and disperse quickly after a distance about 100 ⁇ 150 nozzle diameters downstream the nozzle 51.
  • a suction slot 53 draws air from the left to the right.
  • the air flows around the suction slot 53 are denoted by reference 52.
  • the active suction area is located within a downstream distance from the suction slot 53 to about only 1.5 times diameters of the suction slot 53, as mentioned previously.
  • Individual use of the jet usually lead to early dispersion and individual use of the suction slot usually lead to poor suction capability at the distance beyond the effective suction range.
  • a preferable embodiment of the pollutant removing device includes a first air blow device 6 and a second air blow device 6' respectively located at a front end and a rear end of a pollutant generation source 65 which is installed in a counter top 6".
  • the first and second air blow devices 6, 6' respectively include a first elongate air blow slot 63 and a second elongate air blow slot 64 so as to blow air upward.
  • the first and second elongate air blow slots 63, 64 are respectively located in parallel to the front and rear ends of the pollutant generation source 65.
  • a suction device 61 is located above the counter top 6" to which the pollutant generation source 65 is installed and the suction device 61 includes at least one elongate suction opening 60 which is connected with a suction machine which is not shown.
  • the at least one elongate suction opening 60 is arranged parallel to the first and second elongate air blow slots 63, 64.
  • the number of the elongate suction opening 60 can be two. In a preferable embodiment, there is one elongate suction opening 60 which is located above the first and second elongate air blow slots 63, 64.
  • a rectangular suction device 61 is located at a distance from the counter top 6" and two flanges 62 extend from two sides of the elongate suction opening 60 of the suction device 61.
  • the upward-blowing jets issued from the first and second elongate air blow slots 63, 64 located at the front and rear end of the counter top 6" associated with the upward-drawing suction flow induced by the elongate suction opening 60 form the two inclined air curtains 66, 67 as shown in Figs. 2 and 3 . Because of the existence of the counter top 6", no air can be fed from the underside. A recirculation bubble therefore is formed above the counter top 6" between the two air curtains 66, 67.
  • the air flows inside and outside the recirculation bubble are exchanged by the turbulence diffusion.
  • the air flows above the recirculation bubble are drawn by the suction device 61 and released to outside of the room.
  • the two sides above the counter top 6" are left open or equipped with grids or porous boards through which the compensation air can be naturally provided into the area between the two air curtains as shown in Fig. 3 so that the air flows are steady.
  • a dual-air curtain range hood using the pollutant removing device comprises a first air blow device 7, a second air blow device 7' and a suction device 70, wherein the first and second air blow devices 7, 7' are respectively located at a front end and a rear end of an oven 79 installed on a counter top 77.
  • the first and second air blow devices 7, 7' respectively include a first elongate air blow slot 80 and a second elongate air blow slot 80', the first and second elongate air blow slots 80, 80' are located in parallel to the front and rear ends of the oven 79 and blow air upward.
  • the suction device 70 is located above the counter top 77 to which the oven 79 is installed and includes at least one elongate suction opening 81 which is connected with a suction machine 72.
  • the at least one elongate suction opening 81 is parallel to the first and second elongate air blow slots 80, 80'.
  • the number of the elongate suction opening 81 can be two, preferably, one elongate suction opening 81 is located between the first and second elongate air blow slots 80, 80'.
  • the suction device 70 includes an elongate suction opening 81 which forms a suction opening facing downward and two flanges 71 extend from two sides of the elongate suction opening 81.
  • the suction device 70 is located at a certain height from the counter top 78 so as to provide an upward suction force.
  • the elongate suction opening 81 is connected with a suction machine 72 which is located in the cabinet 75 above the counter top 78 so as to reduce noise.
  • the pipe 721 is opened to outside of the room or is connected to a filter/oil-separation device/oil-collection device and then brings the pollutant out of the room.
  • Two flanges 71 extend from the two sides of the elongate suction opening 81 of the suction device 70.
  • the first and second air blow devices 7, 7' are located at the front and rear ends of the oven 79.
  • the first air blow device 7 and the second air blow device 7' are two cross flow fans which are co-operated with the suction machine 72.
  • the first and second air blow devices 7 and 7' can be two elongate slots and cooperated with a blower (not shown) so as to form two upward-blowing air jets.
  • the air curtain at the rear end of the oven 79 can effectively prevent the grease particles from attaching on the wall on the rear end of the counter top 78.
  • the two sides above the counter top 77 are opened so that air can be sucked into the area between the two air curtains to feed the suction action. By this way, the flow field can maintain nearly "two-dimensional."
  • the two sides above the counter top 77 may have porous boards or grids to allow the air be drawn into the area between the two air curtains with small flow resistance.
  • a smoke is released on the counter top 77 and uses laser-assisted smoke flow visualization technique to trace the flow of the smoke on the planes across the side view, the flow patterns look just similar to that shown in Fig. 2 .
  • the results are shown in Figs. 5 and 6 when no rear wall and the cabinet above the suction device are installed. The status of the air flows in the area is almost identical to the disclosures in Figs. 2 and 3 .
  • the results shown in Figs. 7 and 8 are for the case when there are rear wall and the cabinet installed above the suction device 70. In the mediate portion of the area as shown in Fig.
  • the tracer gas method is used to examine the capture efficiencies of the present invention and the conventional range hood.
  • the suction device is installed at different distances from the counter top and a large upright board swings at 0.35 m/s to simulate air flows generated by fan, or air conditioner or by people walking by the counter.
  • Pure SF 6 gas is provided at constant flow rate by a gas releasing device placed on the counter top.
  • the velocity and concentration of the SF 6 are detected at a remote cross section of the suction pipe.
  • the capture efficiency which is defined as the flow rate of SF 6 passes through the suction pipe divided by the flow rate of pure SF 6 released from the gas releasing device, can be calculated.
  • the result is disclosed in Fig. 9 .
  • the dual-air curtain range hood has much higher capture efficiency than that of the conventional range hood.
  • the ability for reducing the interference by the reference flows of the range hood of the present invention is much higher than that of the conventional range hood.
  • FIGS 10 and 11 show an oil collection device 9 which is removably connected to the elongate suction opening 81 of the suction device 70 so as to collect the oil flowing along insides of the elongate suction opening 81.
  • the elongate suction opening 81 protrudes a little from the flanges 71 and faces downward.
  • the oil collection device 9 is a rectangular box with an open top and includes a base board 91 from which a first side panel 92, a first upright board 93, a second upright board 94 and a second side panel 95 extend upward.
  • a filter 96 is connected to the base board 91.
  • a first space 97 is defined between the first side panel 92, the first upright board 93 and the base board 91, and a second space 98 is defmed between the second side panel 95, the second upright board 94 and the base board 91.
